SEP client reporting to earlier version of SEPM

Hi guys,

I have a scenario. What if SEPM version is 12.1.6 MP1 and client version is 12.1.6 MP5.

Does SEPM version 12.1.6 MP1 will download the virus definition for SEP client 12.1.6 MP5?

I think the SEP 12.1.6 MP5 will still report to SEPM version 12.1.6 MP1 but i don't know if SEPM will provide AV definition to SEP client.

Also it is possible to export installer package with SEP version 12.1.6 MP5?

Thanks in advance.
